I recently installed the following:
- SPA9000 running 6.1.5
- SPA400 running 18.104.22.168
- 4xSPA508G, running 7.4.3, upgraded from 7.1.3
- 2xSPA500S on 2 of the above phones
The setup is really basic, as those devices are connected to an isolated LAN, without any server (DHCP, NTP,...), no IP voice provider currently.
All outside calls are going through the SPA400 gateway, connected to 4 PSTN lines.
I never used the configuration wizard for all that, as the official releases doesn't seem to support the SPA500 series phones.
As in most small businesses, each individual would like to know if an extension is busy prior transferring a call.
Fo that purpose, I configured the BLF extended functions on the IP phone line keys, and it was running fine with release 7.1.3, originally shipped with the phones.
Red fast blinking: ringing
Amber: monitored line not found
Each key is configured using: fnc=blf+cp+sd;sub=stationname@$PROXY;ext=extension@$PROXY
Using the same syntax and release, no BLF status was reported on SPA500S, strange!
I upgraded to correct other bugs,... to 7.4.3
Since the upgrade to 7.4.3, ALL BLF LEDs are turned off a few seconds after each boot on the 2 phones without SPA500S.
On the 2 other phones, with SPA500S, the phone line keys LEDs are not stable, but the SPA500S started to report the correct status.
I then configured one parameter on the 2 phones without any SPA500S attached, changing the attendant console type from Broadsoft to SPA9000, even if no console present. The phone line keys status changed from OFF to unstable, oscillating between green and amber and reversely after a short period of time. As on the two phones with SPA500S.
The SPA500 series admin guide states:
"A monitored extension must be private; not shared. Additionally, an extension can only be monitored by one other extension."
Here, each extension monitors the others. It was however working with 7.1.3, which contradicts this statement, indicating a correct configuration on the SPA9000 side (CTI), and no performance limitation from any hardware.
Can you provide me with the exact capabilities of the devices?
Is this a bug in 7.4.3, will it be fixed?
Is the documentation not correctly written/updated from SPA900 to SPA500?
Was it miraculously working in 7.1.3, for an unknown reason, and this nice feature has definitely disappeared?
Am I wrong with my configuration?
